Two Monitors with QNX computer

Hi,

I need to provide a remote monitor feature for QNX (Photon) based
workstation with a local LCD display. The workstation computer has a local
display that will be utilised by the user for variuos features like mimic
display, report generation, database editor, alarm display, etc. The remote
monitor must display only the latest alarms and alarm history. The remote
monitor will be placed at a distance of about 20meters from the workstation.

I was wondering if it is possible to use two display cards on the same
computer system and configure those for Photon microGUI. Will it be possible
to develop software applications that can be independently run for two
monitors to provide 2 independent displays to the user? What will be the
difference between a normal Photon application running on single display and
the one that will run for two displays?

Thanks,
Krupa

It is quite possible. Your best bet is if the two video cards
are the same model. You need to manually modify the /etc/config/trap/crt.# file.
You need to put two driver lines on the first line separated by a ‘;’ and one
of the drivers will need a -I1 parameter instead of -I0

After configuring dual displays for Photon, how to run two different
programs on those displays?

Thanks,
Krupa

There’s really not much too it. They both are just windows into the same
Photon space. You might need to move a program-window. This can usually be
done with startup parameters.

Is it not feasible to start a private photon session on remote monitor?

It is quite easy. There are three ways to get a program to run on another monitor.

  1. Put it there. I know that this is not what you mean.

  2. Have the program automatically move itself.

  3. Use the standard Photon command line arguments.
